Great small lake
Mancos State Park has no-wake boating and is well-known for fishing, especially rainbow trout, a few brownies and yellow perch. There are 33 campsites on two sides of the lake, plus two all-season yurts. During the winter, it is a great place to use as a base for cross country skiing.
It is near the La Plata range to the east, and Mesa Verde National Park to the southwest. Durango is about 45 minutes to the east, and the City of Cortez about 25 minutes to the west. Telluride ski resort is about a two-hour drive. Both Cortez and Durango are full-service cities, with multiple supermarkets, other chains, etc. The town of Mancos, about a 12-minute drive from the park, has a full-service sit-down restaurant/bakery, a natural foods store, other restaurants, a community grocery store, shops, modern library and other amenities.
The park adjoins the San Juan National Forest, including multiple hiking trails, the Chicken Creek cross country ski area, the Sawtooth and Millwood trails, and other trails. The nearby forest (about a mile up the road) has dispersed camping as well as organized campgrounds accessible by a paved road.
There also is a dude ranch next to the park, and the approximate 1-mile trail around the park takes hikers over some beautiful scenery. There are no corrals, but horses are allowed on specific trails.
None of the campsites currently have water or electric hookups, but potable water is available at several connections on the east (main) side of the park. While there is no public WiFi, cell signals are strong.
